Moxabustion

For thousands of years, practioners of acupuncture would burn mugwort on a patient's skin, believing that the heat would penetrate and help heal the patient.

Superstition is a funny thing.

Often expensive, time-consuming and even dangerous, a superstition can stick around for a long time, even when there's no evidence that it really works.

Everywhere I look, I see organizations practicing moxabustion. With a vengeance.
